Research On Evaluation Of Regional Water Resources Allocation Shemes Based On Multi-objective Group Decision-making

The problem of water resources is a global problem, such as scarcity of water resources, unbanlance of timespace distributing, the contradiction between supply and requirement of water resources, so it is necessary for conducting water resouecs reasonable allocation based on the natural allocation of water resource. Choosing a reasonable allocation scheme including the aspects of economy, society and environment from numerous schemes, we need to carry on evaluation and analysis to every scheme.On the basis of summarizing the research progress of water resources reasonable allocation and schemes evaluation as well as problems in existence, the paper carrys on further research to the evaluation of regional water resources allocation schemes.The multi-layers evaluation index systems of regional water resources allocation shemes are established including four rules such as societyl and economy rationality, environment rationality, resources rationality, exploitation and using rationality by considering sustainable development and the principles of establishing evaluation index systems. Moreover, the sieving principles of evaluation indexes and the methods of combining qualitative and quantitative analysis are studied.The paper describes the multi-objective group decision-making theory of regional water resources allocation schemes evaluation. After concluding some multi-objective evaluation methods, three kinds of evaluation models with multi-objective group multi-layers are studied particularly including the evaluation model based on maximum entropy principle, fuzzy matter-element optimization model, the model based on gray relevant degree and TOPSIS. Furthermore, owing to the group decision-making characteristic with many people participation of water resources allocation, the methods for derivign experts' weighting in group decision-making are studied particularly.Many water resources allocation schemes are obtained by making use of vision-shaved analysis system of water resources allocation based on B/S mode.Those theories and method studied in the paper are applied for the evaluation of water resources allocation schemes in JiNing city, and a reasonable recommending scheme of 2020 is selected, thus verified science and the possibility of those theories and method. Finally, the sustainable development evaluation of the recommending scheme is done,the result shows that the recommending scheme can ensure sustainable development of society and economy, and water resources can harmonize wih the development of society and economy, as well as the projection of environment preferably.
